INTRODUCTION
Thermal-pac™
and
thermal-duct™
air
handlers are designed for use with
hydronic (boiler) systems or in
combination space and water heating
systems (Combo Systems). Combo
heating systems use the home’s water
heater to provide both the space heating
and domestic hot water, eliminating the
need for a furnace.
Combo heating systems are ideally
suited for single-family homes,
townhouses and apartments where the
cost of a furnace does not make sense or
space requirements are limited. They
are also great for additions, renovation
and finished basements as a
replacement for, or in addition to the
existing heating system. Ecologix air
handlers are also great for hydronic
heating systems using ground-source
heat pumps. They are the smallest units
available in their capacity range.
Thermal-pac™
and
thermal-duct™
air
handlers are designed to take the
guesswork out of system sizing and
installation. Matched specifically to
common water heater sizes, Ecologix air
handlers can be quickly sized using the
quick sizing information in our spec
sheets or from air handler performance
curves. For applications requiring
special consideration, call 519-658-
4330 for answers to questions related to
sizing, installation or trouble-shooting for
any of Ecologix air handlers or water
heaters.
Ecologix provides you with the quietest
operating air handler available. By using
large capacity, high output heating coils,
the air handlers deliver more heating per
volume of air, which means warmer
delivered air temperatures.
Thermal-pac™
air handlers are intended
for conventional duct systems and
Thermal
-duct
™ air handlers are
intended for
small-D
™ duct systems with
higher operating static pressure. Refer
to the
small-D
™ design manual for more
details on duct design and installation.
HOW IT WORKS
Cooling
In a typical installation, a call for cooling
will bring on the fan at the selected air
speed and the outdoor cooling unit.
The installer can select one of three
speeds that the air handler will operate at
during cooling mode.
Heating
A call for heating will bring on the pump
and the fan at the selected heating
speed. Heating capacity may be
adjusted by selecting one of three fan
speeds. Heating has priority over
cooling or continuous fan. The factory
default is low.
Continuous Fan
When the thermostat fan switch is set to
continuous fan, the fan will run at the
selected speed. The factory default is
low. When there is a call for heating or
